I need to order a driver's fender and I see two part numbers listed. I have a GT model, but I put a R3 bumper and side skirts on mine. Part number 52210(FFY252200) advises with Large side spoiler, and part number 52210(FFY45220)? advises without side spoiler, w side spoiler small. Are there two different fenders? Where should I buy it from for the best price?

I bought a replacement grill from Jim Ellis Mazda (https://www.jimellismazdaparts.com/s...category=20229) for my R3. Prices were reasonable and the parts shipped quickly (though the USPS did lose it for a few days, so arrival was delayed). My guess is you want FFY252100, but I'd give them a call to find which fender you should get.
